Announcements"Capacity Utilization" Monitoring MetricModification：

Last updated 2023-06-16 10:38:11
To optimize user experience, TencentDB for MongoDB has to modify the statistical method of the monitoring metric"Capacity Utilization" in November, 2020.
The current statistical method calculates the average value of capacity utilization of multiple nodes, while the newmethod will calculate the minimum value of capacity utilization of multiple nodes.
The minimum value also decides whether TencentDB for MongoDB should lock an instance due to the instancecapacity being fully utilized.
During the modification, it is normal if the capacity utilization of your disk is temporarily reduced.
